Felted soaps are a wonderfully versatile item. They are like a soap and washcloth in one, but better. The wool that is shrunken around the soap bar acts like an exfoliant with the additional benefit of moisturization through the lanolin in the wool. It further helps the soap to lather more, and if left to dry in between uses, can help the bar to last longer. Since it is like a soap and washcloth in one, it is especially beneficial for special needs individuals who have difficulty managing a separate soap bar and washcloth.
As the soap shrinks down, the wool shrinks with it. When you are left with just the wool, you can use it as a face scrubbie.
